Admittedly I can't be sure of how much of their wealth is or isn't tied up in the bankruptcy--though I think the same is also true of everyone else here--but if they're anything like most others who own large companies, it represents a significant fraction of their net worth and it's about to be worthless.
Bankruptcy court is pretty much always like this, though. I remember the same kinds of things coming up during, e.g., SCO.
From a Bloomberg article I read, approximately $200 million will come from a family foundation, $3 billion will come from a forced sale of some international companies they own, and the remainder of the settlement from their vast array of trusts and other investments worth...approximately $8-9 billion dollars. So while the settlement is a large amount, it amounts to no practical impact for the family, which is why so many people think it's unjust. They will still have a huge amount of dynastic wealth and will not need to make any changes to their extravagant lifestyles whatsoever. Boohoo, the dynastic wealth will only enable the next 6 generations of Sacklers to be entitled pieces of shit instead of the next 8.
